I'm nearing the end of nameless isle. I already killed the master and turned in his heart to the scion making sebille rooted. Sehalia gave me the quest to kill the mother tree but I can't do anything to it. I tried killing the scion but interacting with the heart just tells me that it looks unwell. I can't attack it. I don't have access to the deathfog bomb because the master is already dead. I see no way to progress forward with sebilles quest. Is it just broken? Does turning in the heart break the quest? Help please!
